TL;DR: In this article, a sulphone or sulphoxide moiety at C-1, C-6 in place of sulphide, ether or amino groups was introduced for hexa-2,4-diynes.
Abstract: 13C NMR data for 1,6-bis derivatives of hexa-2,4-diynes are reported. Introduction of a sulphone or sulphoxide moiety at C-1, C-6 in place of sulphide, ether or amino groups caused a 6–7 ppm upfield shift (β effect) for the C-2, C-5 carbons and a 3–4 ppm downfield shift (y effect) for the C-3, C-4 carbons.
